Compiling and executing GPIB code in Visual basic

[Shonda]

I am writing simple GPIB commands using Visual Basic 6.0 to communicate with my test instruments. All went well until I added an MSComm1 object to my form to send out a text message through COM1. At design time this works fine, but when I make my program executable my test instruments do not want to give any readings back to me. I can change the settings on my instruments programmatically, but it will not respond with any measurements.

Hi,
Are you running the program on a target computer (not the computer you developed on)? If so, you need to make sure that you have VISA installed on your target computer.
